Growth Cycle

Keeping the treatment rythm

As soon as the treatment for a permanent hair removal with the XENOgel technology has begun, it is very important to stick to the next appointments. If you have already planned long breaks, as a vacation or seminars, you should consider them before.

The cycles are different depending on the body region.

4 weeks          armpit, bikini, intimate zone and intergluteal fold

6 weeks          feet, thigh, lower leg, chest, abdomen, buttocks, coccyx, back, shoulder, neck, upper arm, forearm, hands

8 weeks          face, throat, upper lip, chin, head

Why is it so important to comply with the growth cycles?

Every single hair goes through a number of cycles during its growth phase. The important phases for us are the resting phase (telogen phase) and the active phase (anagen phase). During the resting phase, the hair is not connected with the hair root and is therefore not provided with nutrients. It is resting and therefore not growing anymore. In the active phase the hair is connected to the hair root and so is provided with nutrients, thus it grows.


A successful treatment is only possible, if the single hair is in the active phase. Through the connection of the hair with the root, the light of the XENOgel technology manages to get into it and consequently denatures it. Therfore, each hair root is not provided with nutrients anymore, and so each hair falls out.

Only 10% of body hair are in the active growth phase. The remaining 90% of hair are resting. Every hair is about 4 weeks or rather 6, or 8 weeks in the anangen growth phase. After about 9×4 weeks or rather 9×6 or 9×8 weeks, it is in the telogen resting phase. Every hair has its own cycle.

Over an area of 10 cm2 there are for example 1000 hair. Therefore, 900 hair are resting and 100 are growing, where the cycle is in this example 4 weeks. After 4 weeks, there are other 10% of hair in the growth phase. So the treatment cycles are very important, to remove EVERY hair in the relevant area. If the cycle is interrupted, it is impossible to predict when the hair are in the next active phase. Therefore, the whole process has to start more or less from the beginning. Consequently, there are significantly more treatments needed, to remove all hair permanently from the desired area.
